The TRP-C36 Ethernet serial server connects RS-232, RS-422 or RS-485 serial devices to an
Ethernet LAN/WAN providing a reliable communication connection. The TRP-C36 Windows
driver installs virtual COM ports in the Device Manager of the operating system. The virtual COM
port is designed to establish a connection with the TRP-C36. This in turn will allow
communications with the connected serial device in the same manner as a device connected to
the COM port in a PC. The LAN becomes transparent to the serial device and the software
running on the PC. TRP-C36 also offers a Heart Beat feature to insure a reliable communications
connection.
The TRP-C36 can be configured as a TCP Client/Server or UDP. The TRP-C36 operates in
“Paired Mode“, “Virtual COM” Mode”, and “Direct IP Mode”.
8.1 Paired Mode
Paired mode is also called serial tunneling. When this type of configuration is selected, No
additional software is needed to install in a host PC. In fact a PC is not required to make the
connection. Any two dumb serial devices that can communicate with each other through a serial
link will be able to communicate using two TRP-C36 and the LAN.
Two TRP-C36 are configured with one setup as a TCP or UDP client and the other to TCP/UDP
server. When setting up the Server, the Remote IP address section must contain the address of
the Client. This will allow the Client’s IP address to pass the IP address-filtering feature of the
Server. Conversely, the Remote IP address of the Client must contain the Server’s IP address.
How to Setup TRP-C36 paired mode
1. Configure TRP-C36 server.
